To all whom it may concern:

of'Boston, in the county of sufi'olk andg State of Massachusetts, a citizen of the. Uni'ted States have 'inyented a newand usefullm- ;proyelnent in Windows, of whichthe follow- -tingj is a fulhclearfand exaet refer n e n a wit mr i ms 1.d'.ew es lt l n e fir ejii e e si Pl mmg eter "fThB PI BS BIlt ITIIYGHtlOH relates to an mprovement 1n w1ndows and essentially-to a ear window or 0Ile hitV1Ilg a s ngle shdmg sash.

V The object of my invention is particularly to provide for an airtight closure of the window when the sash is occupying aclosed position and at the same time to'perm'itof "an easy opening and closing of the'sash.

The invention can'best be seen and pnderstood by reference to 'the drawi'ngs; fin I A v p v run intoone anotliento form a united inwhich-' Figure 1 is a frontelevat on of a window. 2 is a section onthe line- Q-fi of Fi 1. f%ig. 3 is a section on the line 3 30f ig, tisthe seine esg lf ig. 3 except that the sash isgshown occupy; t ion' as will later be exp aine "Referring to the drawings 1 represents the frame and 2 the sash.

prising a sliding sash, means framing. said. sash to permit the latter to havewhen closed In connection with theconstruction and 0 eration of the device attention is also directed to the fact that during the sliding movement of thesash it is maintained out of contact with the inserts or parts formin the seal, wear 0111 coming uponthe channe bars which in t is connection act I as re placeable wearin parts. 7

Having thus fu ly described m invention, I claim and desire to secure by ttersPatent of the United States i 1. In a window, the combination coman appreciable movement of translation perpendicular to the plane of the sash. and

In a window, the combination comprising a sliding sash, means framing said sash whereby it may have a sliding move ment to open and whereby also the sash when closed mayhave an appreciable movement of translation perpendicular to the plane of the sash, said framing means bearing seal-forming parts extending around the sash and against which .the sash bars are adapted to have bearin means for holding the sash when close against said seal-forming parts, members embracing the sides of said sash and movable translatably therewith and in which the sash isislidable, and means engaging said members whereby the sash will be held outwof contact with said seal-forming parts during theisliding movement of the sash.
